Definition of Hard measles

Hard measles: An acute highly contagious viral disease with
fever, runny nose, cough, red eyes, and a spreading skin
rash. The eight-day measles is the ordinary measles, also
known as rubeola, a potentially disastrous disease. Measles
may be complicated by ear infections, pneumonia,
encephalitis (that can cause convulsions, mental
retardation. and even death), the sudden onset of low blood
platelet levels with severe bleeding (acute
thrombocytopenic purpura) or a chronic brain disease that
occurs months to often years after an attack of measles
(subacute sclerosing panencephalitis). During pregnancy
measles may trigger miscarriages or premature delivery.
Measles can be prevented through vaccination. The disease
is also called (depending on how long you think it lasts)
the seven-day measles, eight-day measles, nine-day measles,
or the ten-day measles, and morbilli. The name measles
comes from the Middle English maselen meaning many little
spots referring, of course, to the rash.
